“Hi,
I`ve noticed that there aren`t many reviews of these headphones out there and I think they are too underrated, maybe because of it`s price. So, let`s get to it.
Style: I think they look beautiful, I would wear the them in the street without any problem, even wearing a suit.
Build Quality: Simply the best out there, I`ve never seen a pair...” --Silver01

“
Okay..well this is my first review..if you may call it so..hence any,,amatuerish mistakes be forgiven..here we go..
So i saved some money(i'm always short of it) for the Vsonic gr02 be..after studying Head-fi posts extensively..and at the moment of commitment, my seller went out of stock. These were just launched on a reputed website here in india..so i decided that i'd get them to satisfy...” --Aakash

“
In 2012, there was a number of newly launched headphone products by JBL. My friend happens to to have bought one of the J55is. Here is brief review on it.
Packaging case for J55i
For a headphone which costs only $79, packaging is up to standard. At least, it doesn’t appear too cheap.
Various items inside the case
A small pocket inside...” --JamesM

“I was looking for a sennheiser HD201, and I can't find it in the market. Finally I choose this headphones because of JBL name and the simple construction. This are very good for a mobile devices that are used to listed music, radio, recordings, etc, they don't have volume or mic to talk.
The sound is amazing for a bottom line model. Here the sensitivy factor is very important for a mobile...” --rickheadfi

“I have tested all JBL BT Headphones.
I am not even sure why.
These are the ONLY one which is worth considering if you look for a good sound. But NOT for the actual price of $270, EVER.
They do not sound so great either. But not bad like the other JBL.
I have found them somehow exciting, with good dynamic, good bass, good highs and decent mids.
They surely are not the most balanced...” --Giogio

“
Let me get some disclaimers out there before I start writing this review. This was the first pair of $30+ headphones/IEMs I bought. I also got them on clearance (50%) so, for what I paid, these are quite a good deal. At retail price, I'm not sure they are a steal.
When I first plugged these in, I noticed the bass was fairly prominent. Now, either I'm getting deafer or the bass has tamed...” --matchless

“
Like all JBL products , performance is the last priority, the S100a does one thing good ..that's rock , the treble is not that grainy , making it excellent for rock , its rolled off too not in a bad way , its the 6XX roll off , almost perfect roll off ....which is very odd for a IEM like the S100a
I really enjoy it , very good indeed ..I think it should sound...” --MrTechAgent

“I got this because I need a new headphone while on commute.
The first thing I noticed is that the bass volume is low but its there specially when you press the cups against your ears.
The trick there is just find the angle where the cups lay flat on the ears when you wear them.
If you wear it like in this photo: the bass is almost non existent.
I say the highs and mids are still good when...” --rexFi

“If I would have to choose between these and the JBL E40, I would probably kill myself.
But in case I am of particularly good mood I would choose these.
They do not have much better SQ but have a somehow more interesting personality, with a proud strong dull bass of no more than decent quality, and bright highs (like all JBL BT Headphones).
They do not lack mids but do not bring...” --Giogio

“Well, I can't really write much more than what I wrote for the E40.
They are the same in everything except that the E50 is bigger and have at least some bass.
Actually, to really be honest, the E50 sound like an AKG K845 with poor detail and no soundstage. Which is probably impressive for the price.
But I still am not impressed.
Personally, unless you really really need to...” --Giogio
